PROCESS OF AND APPARATUS FOR DRAWING AND STRAIGHTENING WIRE.

SPECIFICATION forming part of Letters Patent No. 339,739, dated April13, 1886.

Application filed March 2, 1886. Serial No. 193,758. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL HENRY BYRNE, asubject of the Queen of GreatBritain, residing at Brighouse, in the county of York, Eng- 5 land,wire-manufacturer, have invented certain new and useful Improvements inDressing and Straightening lVire and in Apparatus to be EmployedTherein, of which the following is a specification.

This invention has for its object improvements in dressing andstraightening wire and in apparatus to be employed therein.

At the present time wire is dressed and straightened by drawing itthrough dressingplates with pins between which it is passed in a zigzagcourse. The wire is unwound from one drum, made to traverse thedressing-plate, and wound up again on another drum. This treatment isrepeated again and again. These separate operations give rise to muchloss of time and waste of material.

According to my invention, I effect several successive dressings at oneoperation and without winding the wire into a bundle until the end ofthe operation. Ialso combine dressing apparatus with the wire-drawingbench. After drawing the wire in 'successionthrough a number of dies atone operation, as described in the specification of a former patentgranted to me, the wire, without winding it into a bundle, is caused atonce to pass through the pins of the dressing-plate. One or more sets ofsuch pins are employed, and between the dressing-plates or sets of pins(if there be more than one) the wire is passed around pulleys. Thesepulleys are driven at a suitable speed to bring the wire forward, andthey are arranged with their axes at different angles in relation to thepins, in order that the wire may be dressed in different directions. Onleaving the pins of the last dressing-plate the wire is wound upon adrum into a bundle. I also arrange dressing-machines separately from thewire-drawing bench, and in these, as above described, the wire is passedcontinuously through the pins of several dressing-plates. It is unwoundfrom a bundle at the entrance end of the machine, and wound up againwhen the dressing operation is complete. Between each dressing-plate andthe next the wire is speed. The pulleys and pins are so arranged thatthe wire may be dressed on all sides.

In order that my said invention may be fully understood and readilycarried into effect, I will proceed to describe the drawings hereuntoannexed.

In the drawings, Figure 1. is a side eleva= tion, and Fig. 2 is a planof combined wire drawing and dressing apparatus arranged in accordancewith my invention.

A A is the frame of the machine. B is a main shaft, carried in suitablebearings upon it, and driven by a belt passing around the pulleys B.

O is the belt-fork for starting and stopping the machine.

D D are pulleys of various sizes upon the axis B. Endless cords passingaround these pulleys drive intermediate shafts, E E E.

E E are coned pulleys upon the same shafts, and these by endless beltsactuate other coned pulleys, F F, fixed upon shafts F F at the upperpart of the frame of the machine.

G G G are belt-forks, by means of which the exact position of the beltson the coned pulleys E F can be adjusted, so that the shafts F F F canbe set to revolve precisely at the relative speeds required.

F F F are drums upon the shafts F, around which the wire under processin the machine is wound. The wire is brought to the machine in a bundle,and is placed upon the drum G*. From this it passes to the first of aseries of dies, H H H, each with an eye smaller than that of the diewhich precedes it. The dies are carried in holders, which are rotated bymeans of spur-teeth upon the die-holder, with which pinions I I Iengage; These pinions are upon a horizontal shaft, 1, on which there isaworm-wheel, I".

K is a vertical shaft, carrying at its upper end a worm, K, engagingwith a wheel, 1", and so imparting rotary motion to all the dies. Theshaft K is itself driven by an endless cord, passing around a pulleyupon it and around another pulley on a vertical shaft, L, which isdriven from the main shaft B by pulleys and an endless cord, as thedrawings indicate. The wire drawn from the drum Gr passes through thefirst die H of the series. Then passed around a pulley driven at asuitable it is lapped once or twice around the first drum F This drum,in rotating, draws the wire forward through the eye of the preceding dieH. The wire leaving the first drum F passes through the next die andthen around the next drum, and so on until it arrives at the end of theseries, each die elongating the wire and reducing its sectional area.The drums, as previously stated, have their speeds accurately adjustedto the dimensions'of the dies. After leaving the last die of the series,the wire is lapped around the drum L on the vertical axis L, which drawsthe wire through the last die and transmits it to the dressing-plate M,in which dressing-pins are set in the usual manner, so that the wirelaid between them is slightly deflected froma direct course.

N is another drum on a vertical axis, N, which draws the wire forwardbetween the dressing-pins at M and passes it forward to another set ofdressing-pins at 0. Through these pins itis drawn by the drum 1?, aroundwhich the wire is lapped, and this drum is upon a horizontal axis,1?,ywhcreas the axis of the preceding drum, N, is vertical, and so,also, is the axisB at the succeeding drum, B. Q is a dressing-platesituate between the drums P B, and S is another dressing-plate betweenthe drum R and the drum T, upon which the wire is finally wound into abundle. The axis T of this drum also is horizontal or at an angle,preferably a right angle, to the axis R of the preceding drum. Thesevarious parts are driven from the main shaft B, as the drawingsindicate. From a pulley, B, on the shaft B, an endless band passes to apulley, U, on the axis U. The same axis has a pulley, U", upon it, andthis, by a twisted belt, drives a pulley at the lower end of the axis N.From the axis N the axis R is driven by means of a pair of pulleys and adrivingbelt, as shown.

U and U are other pulleys on the axis U, and these, by endless belts,drive the axes P and T.

By the compound machine shown by these drawings the wires are submittedto several drawing operations and afterward to several successivedressing operations without being wound into a bundle at anyintermediate stage, thereby much waste of material and also loss of timeis avoided.

Although it is most convenient thus to conduct several successivedrawings and several successive dressings simultaneously in oneapparatus, nevertheless it is an important improvement on the presentpractice to combine even a single drawing operation through a single diewith a single dressing operation without winding the wire into a bundlebetween these two operations, which heretofore has been the universalpractice.

Again, even when the wire is not drawn and dressed in the same machine,it is an importantimprovement-on the present practice to-pass the wirethrough the pins of several successive dressing-plates by the aid ofwinding-drums,situate between the dressing-plates, without accumulatingthe wire into bundles between one dressing operation and another. Moreespecially is this improvement found where the axes of thewinding-rollers situate between the dressingplates are arranged atangles the one to the other as represented by the drawings, asthis-insures aperfect dressing of the wire onevery side.

Having now particularly described and ascertained the nature of my sailinvention and in what manner the same is to be performed, I declarethat what I claim is I 1. The improvement in the process of dressingwire which consists in performing succes-' sive dressings at oneoperation by passing the wire through one set of dressing-pins, thenaround a drum on which it"is not wound into a bundle, then throughanother set of pins, then around another drum, and so on for as often asmay be desired.

2. The improvement-in the process of dressing wire which consists inpassing the wire coming from a drum through a set of dressv9o ing-pins,then around a drum on an axis-at an angle to that of the first drum,then through another set of pins, and so on for as often.as may bedesired.

3. The improvement in the process of dress-- 5 ing wire which consistsin causing the wire to pass direct from the die to dressing-pins,through which it is dressed and straightened without winding the wireinto a bundle between the die and the dressing-pins.

4. The combination, ina wire-dressing machine, of a set ofdressing-pins, a drum from which the wire passes to the pins, anotherdrum'whieh receives the wire from these pins and whichhas its axis at anangle to theaxis of the first drum, and a second'set ofdressing-pins'receiving the wire from the second drum, substantially asdescribed.

5. The combination, in a wire-dressingmachine, of a set ofdressing-pins, a drum from which the ,wire passes to the pins, anotherdrum which next receives the wire, and a second set of dressing-pinsreceiving the wire from the second drum, substantially as de scribed.

6. The combination, with a wiredrawing bench, of dressing-pins'placedbetween the die or dies and the drum upon which the wire is wound into abundle, substantially as described.
